zabbix(server)

CainGwiz 2020. 5. 31. 14:39

많은 서버들을 관리하기 위해서는 그 서버들의 상태를 알필요가 있다.

 

하지만, 많은 서버들의 상태를 실시간적으로 확인하기란 시간적/물리적으로도 무리수가 있다.

 

이런 고민과 문제를 해결하기 위해 많은 리소스를 사용하지 않고 많은 서버들을 관리 할 수 있는 오픈소스 네트워크 관제툴(Zabbx)을 간단하게 소개하겠다.

 

Zabbix는 수많은 종류의 네트워크 서비스, 서버 등 네트워크를 통해 하드웨어를 관제하여 관리자에게 장애 발생을 실시간으로 알 수있게 만들어진 네트워크 관리 시스템이다. 

 

저자가 Zabbix 설치시에 사용되었던 OS.Spec 및 MW.Spec 정보는 아래와 같다. 

#--------------------------------------------------------------------------------------------------------
#- OS Spec : Red Hat Enterprise Linux version 8 (HVM), EBS General Purpose (SSD) Volume Type
#- Os Detail : Red Hat Enterprise Linux release 8.2 (Ootpa)
#- MiddleWare Spec
#- PHP : PHP 7.2.24 (cli) (built: Oct 22 2019 08:28:36) ( NTS )
#- MariaDB : Ver 9.1 Distrib 10.4.13-MariaDB, for Linux on x86_64
#- Nginx : nginx/1.16.1(Stable) + OpenSSL 1.1.1c
#- Zabbix : Zabbix 5.0 LTS
#--------------------------------------------------------------------------------------------------------

소개는 여기 까지하며, 본론으로 들어가서 설치 방법(Source)에 대해 기재한다.

 

설치 방법이 다소 복잡 할 수 있으나, 순서대로 진행한다면 클리어 할 수 있을 것이다.
